Acute pain is defined as an unpleasant sensory and emotional experience associated with, or resembling actual or potential tissue damage as a result of a surgical procedure, physical trauma, or as a consequence of a medical condition [1]. The prevalence of moderate-severe pain, defined as pain which significantly interferes with daily living activities, ranges between 27% and 66% in hospitalized pediatric patients and remains inconsistent even in those institutions with excellent resources and good reputations [2,3].

Pediatric convulsive status epilepticus is a neurological emergency requiring termination in a time critical fashion, if permanent brain damage or death are to be avoided. Levetiracetam has been suggested as a potential second line agent for benzodiazepine refractory seizures. This review will examine the evidence for levetiracetam’s efficacy and safety in the management of pediatric convulsive status epilepticus.

Liver masses account for 5 to 6% of pediatric cancer, which includes hepatoblastoma (HBL) along with rare cases of hepatocellular carcinoma (HCC). The most dangerous form of pediatric liver cancer is aggressive HBL, which can be characterized by chemo-resistance and multiple nodules or metastases at diagnosis, all correlating with worse clinical prognosis. Despite intensive studies and a significant improvement in overall outcomes, very little is known about the key molecular pathways which determine the aggressiveness of pediatric liver cancer.

Opsoclonus myoclonus syndrome (OMS), also known as Kinsbourne Syndrome, is a rare disorder affecting the central nervous system. It presents clinically with ataxia, diffuse or focal muscle spasms, and rapid, irregular eye movements.

We are writing to promote a novel Bayesian dynamic borrowing approach, the empirical profile Bayesian estimation, in the published article "Yaoshi Wu, Jianan Hui, Qiqi Deng. Empirical profile Bayesian estimation for extrapolation of historical adult data to pediatric drug development. Pharmaceutical statistics 2020; 19; 787-802. http://dx.doi.org/10.1002/pst.2031."
